IMPROVEMENT IN THE MODES OF CONNECTING PITMEN WITH SHAFTS.

Specification forming part of Letters Patent No. 142,616, datedSeptember 9, 1873; application filed April 19, 1873.

To all whom it may concern:

Be it known that 1, RUDOLPH GLEAVE- LAND, of Oovington, in the county ofTioga and State of Pennsylvania, have invented a new and usefulImprovement in Devices for Operating the Dashers of Ghurns, or for otheranalogous purposes; and I do hereby declare that-the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing forming a part of this specification.

I will illustrate my invention by describing it in conncctionwith achurn.

' Figure 1 is a detail vertical section of a churn taken through theline 60 m of Fig. 2. Fig. 2 is a top view of the same. Fig. 3 is adetail view of a bar for connecting the churnshaft with the shaft of adriving power.

The invention consists in the mode of relatively constructing abarandhand crank shaft, so that other power than that of the hand may beemployed to operate, in the manner hereinafter described.

AB represent a churn-body having a socket or pivot, O, to receive thelower end ofa dashershaft, D E, and a cover, F, made in two unequalparts hinged to each other. To the upper end of the shaft D isdetachably attached a bevel-gear wheel, G, the teeth of which mesh intothe teeth of the bevel-gear wheel H attached to the horizontal shaft I.One journal of the shaft I revolves in a hole in the upper end of a bar,J, attached to the churn-body A,

and its other journal revolves in a notch in the upper end of a similarbar, K, attached to the opposite side of said churn-body, where it isheld in place by a spring-catch, L, also attached to said churn-body.One end of the shaft I projects, is flattened, and has a longitudinalslot formed in it, as shown in Figs. 1 and 2. M is a crank, in which isformed a slot to receive the flattened end of the shaft I, so that thechurn may be operated by handpower when desired. N is a bar, in one endof which is formed a slot to receive the flattened end of the shaft 1,when it is secured in place by-a spring catch pin, 0, as shown in Fig.3. The other end of the bar N is slotted to receive the end of the shaftof the driving power, where it is secured in place by a bolt and nut, P.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The bar N slotted at both ends, in combination with spring catch-pin Oand end-slotted end-flattened shaft I, to enable power to be applied tothe latter, as described.
